Important Safety Note
Important Safety Note
Read and understand all the instructions before using the HT-Shaver24VDC

The HT– Shaver should only be used for the purposes for which it
was designed. Use it for no other purpose (e.g. it is not a grader blade
or battering ram!). We have manufactured the HT-Shaver using quality materials and manufacturing techniques however if faults do occur
please have them corrected before you use it.

Please read the Power Head instruction book before use. Pay particular attention to running in and safety notes.

Please read this instruction book before use and retain it for future
reference.

It requires only one person to operate the HT-Shaver - keep all others
away!

Immediately after turning the power head off, fit the cutter bar cover.
It should be removed last, before restarting the power head.

Pull / push pin
Fine adjustment is used when harvesting the crop. It is with a pin—in—hole
type of adjuster and there is one on each side of the harvester. Push in the
blue part and pull out the pin. In relation to the bottom chassis, slide the
conveyor frame forward for lower cut height and rearwards for a higher cut.
Use the handle on RH rear of conveyor to push / pull the conveyor.

7. The speed control can now be used to propel the harvester to the harvest
zone. The drive system can be disengaged with the lever on the drive
gearbox (see picture top of page 7). This allows the harvester to be towed
or simply pushed along. With the drive system engaged 1 or 2 wheel drive can be selected using the free wheeling hub inside the
left hand wheel. Pull knob out slightly and
turn 90degrees to engage. Disengaging is the
reverse. The harvester may have to be
moved a little for the drive to fully engage.

Maintenance

Wash down the HT-Shaver-24VDC harvester carefully after use.
Only wash enough to remove dirt. Over washing will lessen the conveyor belt life. It could also induce corrosion or get into the electrics
and cause problems. Don’t blast water into connections or electrical
components. Sealed bearings are utilised but water under pressure
could penetrate them.

Freighting
Freighting
Freighting on the back of a utility vehicle is preferred. The HT-Shaver is very
light and if transporting on a trailer it is not heavy enough by itself to make the
trailer springs work i.e. it will get badly shaken about. On rough road / tracks this
could cause structural damage. One solution is to put a extra weight on the trailer
as well as the harvester so the springs actually work!
